To all whom it may concern:

Be it known that I, JOHN GAISSER, a citizen of the United States, and a resident of Glendale, in the county of Queens and State of New York, have invented certain new and useful Material Suitable for Wall- Coverings and other Purposes, of which the following is a specification.

The object of my invention isto provide a material which may be used in place of plaster or tiles in covering or finishing walls and the same is useful wherever a hard, smooth-surface material is desired. The material ma be applied directly over the laths of a wal in place of the ordinary wall plaster. It may be applied as a finishing covering to plaster board. It may be made in shapes to resemble tiles and applied the same as tiles or in any other manner. It may be applied to a wall and then marked with grooves before it has completely hardened, in order to make the finished covering resembletiling. The material may be troweled, molded or cast in any desired shape and for various uses, and it may be applied and will set without the use of heat. It has a hard, smooth surface of fine texture and it is not easily fractured or chipped. The material may be made water rggf and it may have coloring mattenifi'c'orporated therein or the surface may be painted after the material has set.

I shall state herein the materials used in making my'new composition of matter and satisfactory and economical without intend- I mix together ten parts of Sn erfine or 40 double calcined ceme t and four parts of hyrate ime. ese 1n hemselves wil1- ro- H'uce a very satisfactory not but I p fer Specification of Letters ratent.

to incorporate additional substances. To the above I add a hard, earthy substance to render the product hard and to improve the surface. For this purpose I mix with the cement and h drated lime two parts of marble dust. his makes the product very msmooth, glossy surface.

If the product is to be waterproof I add to the above one part of commercial waterroofin material which may consist of the commercial product known as Medusa.

Any of the other 0mg powders may be used instead of the one named.

To the above materials, properly mixed, I add sufiicient water to give the proper consistency. If tmuct is to be applied as a wall covering it may be made quite thick whereas for other uses it may be made much thinner.

If the product is to be colored I prefer to mix with the powdered material before the water is added, mineral coloring matter free of oil. If desired, the material may be colored after it has set by painting the surface the same as with any other wall covermg. V v

Having described my invention, what I claim is:

1. A plastic composition consisting of approximately ten parts of superfinerement, four parts hydrated lime, two parts marble dust, and water.

"2. A plastic composition composed of approximately ten parts of superfine cement, four parts of hydrated lime, two parts of marble dust, one part waterprggfipg ppwder, and water. WM
